ATENT ROCKING-CHAIR.

SPECIFIGATIOR' forming part of Letters Patent No. 540,87'7, dated June 11, 1 895.

Application filed January 9, 189 5. $eria1N0.534,367. (No model) likeletters and numerals on the drawings representing like parts.

This invention has for its object to provide a rocking chair withsprings, and supports therefor which in addition to providing points ofattachment for the springs,'restrain the rocker from moving along therockerframe, or base supporting it.

In accordance with this invention the rocker-frame or base whichsupports the rocker,

comprises two parallel bars, preferably grooved at their upperrsides toreceive the rockers, said bars resting upon suitable supports, and thespring supports, two preferably being employed, each comprise twomembers,

the lower one being formed integral with or secured to therocker frame,as to the rockersupportiug bar for instance, and the upper one beingpivotally connected to the rockerframe, as to the rocker-supporting barfor instance, and the forward end of the upper member is looselyconnected to the rocker, so that that as the rocker rocks, the uppermember will be moved up and down on its pivot. The upper end of thespring is connected to the upper member, and the lower end to the lowermember, and in order that said spring may be adjusted toward and fromthe pivot of the spring support, each member is provided with two ormore points of attachment.

Figure 1 shows in vertical section a rockingchair embodying thisinvention; Fig. 2, a plan view of the base provided withrocker-supporting bars and supports or connections for the springs; Fig.3, a rear end view of the rocker-supportingbars and parts connectedtherewith; Fig. 4, a modified form of spring-support, to be referred to;Fig. 5, a vertical section of a rocking-chair, showing another modifiedform of spring-support; Figs. 6 and 7, under side and plan views of thespring-support shown in Fig. 5.

The base of the chair consists essentially of the side pieces a, a, andtranverse connecting pieces a, a. Bolted to said cross pieces a,

a, are two metallic rocker'supporting bars I), 1), arranged inparallelism with and adjacent to the side pieces a, the heads of thebolts by means of which they are secured to the bars being countersunkin the bars. A rockerframe is thus formed.

Each metallic rocker supporting bar I) has cast integral with it aslotted or other car or lo I) located near its rear end, to which ispivotally connected a curved or bent arm 0, said arm extending forward,and being loosely connected at its forward end with the rocker d, or itmay be the chair body, by means of a link 0'. The arm 0 has formed in oralong its under side two lugs 2, 3, side by side, to provide separatepoints of attachment for the upper end of the spring e, one point, as3,being nearer the pivotal connection of the arm than the other. Thisarm 0 constitutes the upper member of the spring support. A lug b isalso cast integral with each metallic rocker-supporting bar Z), whichprojects downwardly for a short distance, then at right angles in adirection toward the front of the chair, as shown in Fig. 1. The lug bis formed with two notches 4, 5, located beneath the lugs 2, 3, toprovide separate points of attachment for the lower end of the spring e,more or less distant from thepivotal connection of the arm '0. This lug19 formed integral with or attached to the rocker-frame, as to therocker-supporting bar for instance, constitutes the lower memberof thespring-support.

The upper side of each metallic rocker-supporting bar b is grooved toreceive the rockers cl, and in the present case the rockers are circularin cross section, and the grooves in the bars correspondingly shaped.There are material advantages gained by employing me tallicrocker-supporting bars, grooved to receive the rockers, as for instancesuppose these bars were made of wood they must be made of wide stock tosupport the rocker, and

if grooved to receive a circular rocker the edges are liable to splitoff if the rockers should swerve ever so little, and they must also bemade of considerable thickness to provide a good and efficient supportfor the pivotal connection of the arm 0; and for the lug b or itsequivalent, and as a result. a bar with these parts attached to itpresents a very clumsy and otherwise unsightly appearance.

By referring to Fig. 4, the upper part or member of the spring-supportis the same as shown in Figs. 1 to 3, but the lower part or member isrepresented as two separate lugs or hooks c 0 formed integral with therockersupporting bar, at points directly below the, lugs 2,3, andserving as points of attachmentf i and rocker-frame, and adjustabletoward and for the lower end of the spring.

Referring to Figs. 5 to 7, the upper part or member 0 of thespring-support is the same as shown in Fig. Land the lower part consistsof a plate or bar, cast or otherwise formed with a hookf, notched at. 4,5, to .receive the lower end of the springe, an ear f by means of whichit is secured to the under side of the-'rocker-supportingbar, and an earf extending upwardly to which the upper part c is pivoted. This lowerpart is placed against the inner sideof the rocker-frame or bar,and'secured by ascrewipassing through said ear f and another screwpassing through the plate into the side of the frame. The

rocker-frame is made of Wood and its :rocker- 'supportin g bars havefiat tops.

These modificationscome within the spirit andscope of myinvention.

1. In a rocking chair, thecombination of a rocker and rocker-frame, .aspring-support.

comprising an upper partipivotally connected at its rear end to afixedpointon the rocker frame,'and loosely connected at its front endwith the rocker, a lower part on the rockerframe, thespring e connectingthe parts, the said spring-support restraining the rocker frommovingalong therocker-frame, substantiallyas described.

2. In arocking chair, the combinatiom of a rocker and rocker frame, aspring-support comprising an :upper part having =lugs 2,3, at a pointbetween its ends, and pivotallyconnected at its rear end to a fixedpoint on the rocker frame, and loosely connected at its front end withthe rocker, and a spring d, the upper end of which is attached to one ofthe hooks on the upper part, and the lower end of which is attached to afixed point on the rocker frame, directly beneath its upper endattachment, substantially as described.

In a rocking chair, the combination of a rocker and rocker-frame, arm 0pivotally connected at its rear end to the rocker frame and looselyconnected at its front end to the rocker, spring e interposed bet weenthe rocker from the pivotal connection of said arm a, substantiallyasdescribed.

4. In a rocking-chair, two metallic rockersnpportingrbarsb,b,having castintegral therewith ears I), and spring-supporting arms a,

, pivotedattheir rear ends to said ears and connected loosely at theirfront ends to the rockers of the chair, substantially as described.

the upper ends'of .the springs c, substantially as described.

6. .In a rocking chair, two metallic rockersupporting bars 11, b groovedat the upper sides, and having cast integral therewith ears '1), andlugs 11?, spring-supporting arms 0, pivoted to the ears, and sprtn gs econnecting said arms with the lugs b substantially as described.
